Objective:
Screen potato varieties for zebra chip disease resistance and assess risk of the disease developing in stored potatoes resulting from late liberibacter infection.

Approach:
Conduct controlled insect exposure experiments under field cage conditions to determine whether potato varieties and advanced breeding lines are resistant to zebra chip potato disease. Conduct controlled insect exposure experiments under field cage conditions late in the season to determine whether symptomless potato tubers produced by late liberibacter infected plants will develop zebra chip symptoms in storage.
